Proportional change in KEGG category abundance between expressed and non-expressed gene fractions. Data are shown for DNA datasets from five representative samples. Unfilled stars mark KEGG k2 categories in which the direction of change was consistent across all five samples. Small filled stars mark categories that did not differ significantly in relative abundance between expressed and non-expressed gene fractions (P > 0.05, chi-square). Only the 25 most abundant KEGG categories are shown.
